Recent Releases of Open-Meteo

Open-Meteo - 1.4.0 Important changes to the Open-Meteo file format

Important The underlying Open-Meteo file format has been upgraded to support future features. This change impacts only users of the open-data distribution on AWS and does not affect those using the API or running downloaders directly.

With this update, the API can now read both legacy and new file formats. Currently, only legacy files are available on AWS, but starting January 14, 2025, files in the new OM format will also be published on AWS. Users of the AWS distribution must upgrade their Docker images to version 1.4.0 or later.

The new Open-Meteo file format is designed to be more flexible and compatible with standards, similar to formats like NetCDF4 or HDF5. We are working on client libraries that will allow users to access curated Open-Meteo weather data directly from AWS S3, enabling data scientists to analyze data at large scales, such as entire countries or continents, without interacting with the API for individual data pieces.

This release marks the first step toward this vision, preparing Docker image users for the new file formats. Development of Python, Rust, and TypeScript libraries is ongoing and will take some time to complete.

Open-Meteo - 1.0.0

🎉🎉🎉 Exciting News! The Open-Meteo source code has officially reached version 1.0.0, marking a significant milestone. This release introduces a stable distribution for both Docker and Ubuntu packages, ensuring a more seamless and reliable deployment experience! 🎉🎉🎉

Major changes include a restructuring of the internal database layout and the incorporation of new weather models. The redesigned database layout is geared towards long-term stability, ensuring compatibility with future versions.

‼️ Important Notice: For users upgrading from previous versions utilizing Docker or Ubuntu Prebuilt packages, it is important to execute a database migration script to preserve previously downloaded weather data. Additionally, many weather models and variables have undergone renaming for consistency. Refer to this PR for detailed information. ‼️

Version 1.0.0 also establishes the groundwork for redistributing the Open-Meteo database as open-data through an AWS Open-Data Sponsorship. Instead of directly downloading raw weather data in GRIB format from national weather services, users can now access the optimized time-series database from Open-Meteo directly through AWS. The open-data distribution allows fine control, enabling users to retrieve only a specific subset of weather variables relevant to their use case. This not only conserves resources for data processing but also reduces bandwidth usage on the servers of national weather services. Instructions can be found in the getting started guide and the open-data documentation. Please be aware that not all weather models and data sources are currently available and will be progressively added over the next few weeks with documentation and examples to follow.

We sincerely appreciate your continuous support and trust that you'll find immense value in the latest enhancements introduced to the Open-Meteo weather API!

About the Open-Meteo Weather API: Open-Meteo is a weather API that operates on an open-source basis and provides free access for non-commercial purposes. No API key is necessary; you can start using it right away!

At Open-Meteo, we firmly believe that access to accurate and dependable weather data should be accessible to all. That's why we've developed an open-source weather API that utilizes weather forecasts derived from open-data sources offered by national weather services. Unlike other weather APIs, Open-Meteo grants complete access to its source code, and all data sources are openly acknowledged, giving credit to the national weather services for their valuable contributions. Users can set up their own weather API rapidly using Docker or prebuilt Ubuntu packages. By sharing the source code, users can thoroughly scrutinize the weather data processing and even make adjustments as needed. We actively encourage and welcome contributions from our user community.

This API is freely available for non-commercial use, with no associated costs. Despite being free of charge, it delivers top-tier forecast accuracy. Leveraging an extensive range of local weather models with frequent updates, the API ensures the generation of highly precise forecasts for locations worldwide.

We appreciate your consideration of Open-Meteo for your weather data requirements. We are continuously working to enhance our services and are open to any feedback or inquiries you may have. Please do not hesitate to reach out to us at [email protected].

Open-Meteo - 0.2.89

The latest iteration of the Open-Meteo weather API has been released! In recent weeks, we've implemented a series of minor enhancements aimed at bolstering accuracy, dependability, and overall performance.

One particularly noteworthy upgrade is the incorporation of 15-minute data derived from the German DWD ICON-D2 and NOAA HRRR models, substantially enhancing the precision of short-term forecasts. Further details on this can be found in our blog post.

We extend our gratitude for your ongoing support and trust that you will find great value in the latest enhancements introduced within the Open-Meteo weather API!

Open-Meteo - 0.2.69 Improvements and bugfixes

The new version of the Open-Meteo weather API is now available! Over the past few weeks, we have made several small improvements to enhance accuracy, reliability, and performance.

One notable improvement is the enhanced accuracy in calculating the position of the sun, resulting in more precise forecasts of direct solar radiation on a normal pane (DNI). Additionally, sunrise and sunset times are now accurate down to the minute.

Behind the scenes, we have given a major update to the Open-Meteo API documentation. It now features a fast and user-friendly web interface built with SvelteKit. This update makes it easier for users to navigate through the wide range of weather variables and parameters.

We would like to express our gratitude to our initial customers who have subscribed to the commercial API SaaS plan. Thanks to their support, we have deployed additional servers in Europe and North America. This expansion ensures better reliability and faster access to weather data, regardless of your location. Furthermore, it allows us to provide weather data to the general public for non-commercial use.

Thank you for your continued support, and we hope you enjoy the latest improvements in the Open-Meteo weather API!

Open-Meteo - Automatic timezone resolution, new APT repository

With this release, timezones can be automatically resolved by coordinates. Instead of manually setting the timezone like &timezone=Europe%2FBerlin, automatic resolution can be enabled with &timezone=auto. The default remains GMT+0. Timezone lookups are available as dedicated library here: SwiftTimezoneLookup

Additionally, the prebuild ubuntu packages are now moved to a different URL. Previously GitHub pages was used, but the large binary files will cause issues in this git repository. The new APT repository url is simply: https://apt.open-meteo.com. The getting started guide has been updated.
